Packages (sometimes called libraries or modules) are re-usable code which you can download, install and then use in your programs.
There is a huge collection of Python packages which you can use with Mu.
Mu comes with its own package installer which will download the code from the Python Package Index pypi.org and install it so you can use it in your Mu projects.
To install packages your computer will need to be connected to the internet and able to access pypi.org.
To install a package:
guizero
and click OK.Multiple packages can be installed by placing the name of individual packages on new lines e.g. to also install adventurelib
you would add a 2nd line and click OK.
Packages can be uninstalled by removing the package name from the list and clicking OK.
